The number of names missing from Upper Clutha war memorials has risen to five.
A Wanaka group looking into the backgrounds of soldiers listed as having been killed in World War 1 discovered three of the McMenamin brothers Charles, James and John, who were born in Wanaka, did not appear on any of the Upper Clutha's memorials.
Now, the group has been given another two names, Privates Alexander Jones and Thomas Little, both of Cardrona.
Wanaka historian Margaret Tomlinson told the Otago Daily Times the names of the two young men appear in a history of Cardrona but not on any memorials.
Cardrona does not have its own memorial but several soldiers from that district killed during the war have their names on other Upper Clutha memorials.
One of those researching the memorial names, Ken Allan, of Wanaka, said it was not too surprising mistakes were made when memorials were erected.
''It's easy to make mistakes. It happens in life everywhere.''
He recalled his own father, who served in World War 2, had his name misspelled on plaques in the Hall of Memories at Waitaki Boys' High School, in Oamaru.
In addition, three names were also missing from the WBHS plaques.
The plaques had been corrected once the errors were pointed out, he said.
Mr Allan believed the same should apply to Upper Clutha memorials that had incorrect information.
Publicity in the ODT about the group's work on memorial names had led to one mystery being cleared up.
A Josiah Brown, who lived and worked in Tarras but had also worked in Luggate, is believed to be the J. Brown on the Hawea Flat memorial and might also possibly be the T. Brown on the Wanaka memorial.
Mr Allan said it was not unusual for people a century ago to be known by a name other than the one in official records.
He gave as an example an Upper Clutha soldier who had dropped the name Bernice and another that seemed to have stopped using Egnatious.
